A set of tools is provided herein that produces useful, proven, and correct integrated semiconductor chips. Having as input either a customer's requirements for a chip, or a design specification for a partially manufactured semiconductor chip, the tools generate the RTL for control plane interconnect; memory composition, test, and manufacture; embedded logic analysis, trace interconnection, and utilization of spare resources on the chip; I/O qualification, JTAG, boundary scan, and SSO analysis; testable clock generation, control, and distribution; interconnection of all of the shared logic in a testable manner from a transistor fabric and/or configurable blocks in the slice. The input customer requirements are first conditioned by RTL analysis tools to quickly implement its logic. The slice definition and the RTL shell provides the correct logic for a set of logic interfaces for the design specification to connect. The tools share a common database so that logical interactions do not require multiple entries. The designs are qualified, tested, and verified by other tools. The tools further optimize the placement and timing of the blocks on the chip with respect to each other and with respect to placement on a board. The suite may be run as batch processes or can be driven interactively through a common graphical user interface. The tools also have an iterative mode and a global mode. In the iterative mode, one or more of the selected tools can generate the blocks or modify a design incrementally and then look at the consequences of the addition, or change. In the global mode, the semiconductor product is designed all at once in a batch process as above and then optimized altogether. This suite of generation tools generates design views including a qualified netlist for a foundry to manufacture.

Suite of tools to design integrated circuits

The present invention provides a comprehensive design environment defining a system architecture and methodology that may integrate interconnects, cores, ePLC, re-configurable processors and software into a manageable and predictable system designs that achieve on-time system IC design results meeting desired specifications and budgets. For example, an interscalable interconnect maybe provided that is scalable and isochronous capable. Additionally, an abstract language may be provided to be able to describe interconnecting core functions. Further, a self-programmable chip may be provided that, upon receiving a construct, it could program itself to achieve the desired functionality, such as through the use of on-chip knowledge and the like.

A computer network is disclosed comprising a plurality of interconnected computer devices including a plurality of disk drives for storing network data, each disk drive comprising a head and a disk. The computer network comprises a plurality of interconnected nodes, and a reservation facility for reserving resources within the disk drives and the nodes to support a predetermined Quality-of-Service constraint with respect to data transmitted between the disk drives through the nodes of the computer network. In one embodiment, a switched node is disclosed comprising switching circuitry having more than two bi-directional ports for simultaneously transmitting data in multiple dimensions through a computer network, a disk for storing data, a head actuated over the disk for writing data to and reading data from the disk, and a reservation facility for reserving resources associated with data read from the disk and written to the disk to support the predetermined Quality-of-Service constraint with respect to data transmitted through the computer network.

A distributed method of establishing a path in a multi-dimensional computer network comprising a plurality of nodes for transmitting isochronous data from a source node to a destination node is disclosed. A request packet is injected into the network, the request packet specifying a request to transmit the isochronous data from one of a plurality of source nodes. The request packet is routed to at least one the plurality of source nodes, and the source node determines whether it has sufficient resources to support transmitting the isochronous data. If the source node comprises sufficient resources to support transmitting the isochronous data, the source node reserves resources within the source node to support transmitting the isochronous data, and transmits an ack packet from the source node to a first neighboring node. The first neighboring node determines whether it has sufficient resources to support transmitting the isochronous data. If the first neighboring node comprises sufficient resources to support transmitting the isochronous data, the first neighboring node reserves resources within the first neighboring node to support transmitting the isochronous data, and transmits the ack packet to an adjacent node. If the first neighboring node does not comprise sufficient resources to support transmitting the isochronous data, the first neighboring node transmits a nack packet to the source node and the source node transmits the ack packet to a second neighboring node.

Interscalable interconnect

This invention is directed to a method for processing file system service requests in a computer having an attached disk drive that in response to commands from the computer can write data to or read data from disk locations to reproduce stream data and non-stream data. The method comprises the steps of responding to a first file system service request by recording whether the first file system service request is for non-stream data or stream data, associating a first set of disk locations of the disk drive with the first file system service request, and preparing a first command that requires access to the first set of disk locations, the first command including control data categorizing the command as a non-stream access command or as a stream access command in response to the step of recording. The method includes transmitting the first command to the disk drive.
